What is spunbond non-woven fabric? What is the difference with non-woven fabric?

 　 Affiliation: Spunbond non-woven fabric is a kind of non-woven fabric.

Non-woven fabric is a kind of fabric that does not need to be spun and weaves, but only oriented or randomly braided textile short fibers or filaments to form a fiber network structure, and then reinforced by mechanical, thermal bonding or chemical methods. . To put it simply: it is not interwoven and knitted together one by one yarns, but the fibers are directly bonded together by physical methods, so when you get the sticky scale in your clothes , You will find that it is impossible to draw out the thread ends. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.

　　 Its main uses can be roughly divided into:

　　 (1) Medical and sanitary cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, women’s sanitary napkins, etc.;

　　 (2) Cloths for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.;

　　 (3) Follow-up cloth: lining, fusible interlining, wadding, styling cotton, various synthetic leather base cloths, etc.;

　　 (4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc.;

　　 (5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;

　　 (6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.

　　 Classification of non-woven fabrics:

　　 One, spunlace non-woven fabric

　　The spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength.

　　 Two, heat-sealing non-woven fabric

　　Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement material to the fiber web, and the fiber web is heated, melted and cooled to reinforce the fabric.

　　 3. Pulp air laid non-woven fabric

　　 Airlaid non-woven fabric can also be called dust-free paper, dry paper-making non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth.

　　 Four, wet non-woven fabric

The wet-laid non-woven fabric is to open the fiber raw materials placed in the water medium into single fibers, and at the same time, the different fiber raw materials are mixed to form a fiber suspension slurry. The suspension slurry is transported to the web forming mechanism, and the fibers are formed into a web in a wet state. Reinforce into cloth.

　　 Five, spunbond non-woven fabric

Spunbond non-woven fabrics are formed after the polymer has been extruded and stretched to form continuous filaments. The filaments are laid into a web, and the web is then bonded through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. The web becomes a non-woven fabric.

　　 Six, melt blown non-woven fabric

　　The process of melt-blown non-woven fabrics: polymer feeding---melt extrusion---fiber formation---fiber cooling---forming net---reinforcement into cloth.

　　 Seven, needle punched non-woven fabric

　　 Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the piercing effect of needles to reinforce the fluffy web into a fabric.

　　 8. Stitched non-woven fabric

Stitched non-woven fabric is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to align fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or a combination of them. The body is reinforced to make a non-woven fabric.
